DrawAnywhere — Open Source Productivity App

DrawAnywhere lets you sketch, annotate, and highlight directly on top of any screen. Great for following along video courses, recording tutorials or hosting presentations. Highlights:

• Stroke eraser toggleable via stylus buttons
• Touch passthrough to the app below
• 50-step undo/redo operations
• Minimal storage usage

Tips:

• Long press and drag to move the toolbar around.
• After 3 seconds of inactivity, the toolbar becomes more transparent.
• Turn on Clear on hiding canvas to let the app clear the canvas when you hide it.
  Note: Touch passthrough will be turned off automatically as well.
• Turn off Canvas visible on start to hide the canvas on startup by default.
